Who is to blame.

No, I think it's fair game to ask why this or that person or group of persons supports this or that candidate. Doesn't mean that association will decide my vote, but it may inform it if there's relevance to my concerns.

That's not what the slanderers are doing. They are saying that all voters for one candidate must always share the same values and reasons for supporting that candidate.

I'm on the record in this forum as stating that not all, or even a majority, of Trump voters are necessarily bigots.

Having said that, it is entirely fair to ask why those who are bigots support the man, and to take that into account.
